I am trying to generate a continuous sawtooth ramp from 2-4GHz. I am considering the ADF4159, but it looks like I will need a few external components. Can this be accomplished using the evaluation board for the ADF4159? Can you suggest a VCO and anything else that would be needed for this application? Here's what I need:
· Programmable start and stop frequency
· Low phase noise
· Ramp from 2-4 GHz
Additionally, let me know if there is a better part/solution.
